ACM, the world's largest educational and scientific computing society, delivers resources that advance computing as a science and a profession. ACM provides the computing field's premier Digital Library and serves its members and the computing profession with leading-edge publications, conferences, and career resources.

ACM offers the resources, access and tools to invent the future. No one has a larger global network of professional peers. No one has more exclusive content. No one presents more forward-looking events. Or confers more prestigious awards. Or provides a more comprehensive learning center.

For more than 60 years, the best and brightest minds in computing have come to ACM to meet, share ideas, publish their work and change the world. ACM's publications are among the most respected and highly cited in the field because of their longstanding focus on quality and their ability to attract pioneering thought leaders from both academia and industry.

ACM's Special Interest Groups (SIGs) represent major areas of computing, addressing the interests of technical communities that drive innovation. SIGs offer a wealth of conferences, publications and activities focused on specific computing sub-disciplines. They enable members to share expertise, discovery and best practices.

ACM’s Professional and Student chapters worldwide serve as hubs of activity for ACM members and the computing community at large. They provide seminars, lectures, learning forums and networking opportunities with peers and experts across the computing spectrum.

ACM recognizes excellence through its eminent awards for technical and professional achievements and contributions in computer science and information technology. It also names as Fellows and Distinguished Members those members who, in addition to professional accomplishments, have made significant contributions to ACM's mission.

ACM’s educational activities, conducted primarily through our Education Board and Council, range from the K-12 space (CSTA) and two-year programs to undergraduate, graduate, and doctoral-level education, and professional development for computing practitioners at every stage of their career...

ACM provides independent, nonpartisan, and technology-neutral research and resources to policy leaders, stakeholders, and the public about public policy issues, drawn from the deep technical expertise of the computing community.

ACM encourages its members to take a direct hand in shaping the future of the association. This philosophy permeates every level of ACM, reaching to the top echelons of leadership where members fill vital positions on the councils, boards and committees that govern the organization and raise the visibility of ACM worldwide.

Rashid and Tevanian Led Mach's Development as an Innovative System for Widespread Commercial Use

NEW YORK, NY, April 20, 2015 –
ACM, the Association for Computing Machinery, today announced that Mach, a pioneering operating system used as the basis for later operating systems, has won the prestigious
ACM Software System Award. The lead developers, Rick Rashid and Avie Tevanian, created a system that advanced the state of operating systems and led to practical, widespread adoption. Mach-based operating systems are used by hundreds of millions of people 30 years after the project began. ACM will present this and other awards at the ACM Awards Banquet on June 20 in San Francisco.

The Mach operating system, a DARPA-funded research project at Carnegie Mellon University conducted from 1983-1992, was based on innovative approaches to virtual memory management and microkernel architecture. Under the leadership of Rashid and Tevanian, Mach established a foundation for later operating systems on personal computers, tablets, and mobile phones. Rashid founded Microsoft Research in 1991, and is Vice President and Chief Technology Officer for Microsoft Applications and Services Group. Tevanian, formerly of Apple Inc., is Managing Director of Elevation Partners, a private equity firm.

Mach’s influence reflects both significant commercial acceptance and substantial contributions to the concept of operating systems. For example, Mach’s portability and performance attributes made it possible for Apple to rely extensively on it in their operating systems for their devices.

The Mach kernel forms the heart of the Apple iOS and OS X systems. Mach was at the core of NeXT’s operating system, which Apple acquired and subsequently used as the basis of OS X and iOS. Mach’s influence can also be traced to operating systems such as GNU Hurd, and UNIX systems OSF/1, Digital Unix, and Tru64 Unix.

About the ACM Software System Award

The
ACM Software System Award honors an institution or individual(s) recognized for developing a software system that has had a lasting influence, reflected in contributions to concepts, in commercial acceptance, or both. This award carries a prize of $35,000. Financial support for the award is provided by IBM.
